Mounting device for object to be mounted

Abstract

A mounting device includes a slope including: a main plate for mounting a wheelchair; a vehicle-side plate provided between a vehicle and an edge of the main plate and having at least one plate; and a ground to be contacted-side plate provided between a surface of ground to be contacted and the other edge of the main plate and having at least one plate. The main plate can be raised and lowered between low and high positions when the ground to be contacted-side plate is in contact with the ground. The mounting device is also provided with: an electric winch that can tow the wheelchair along the slope; a slope driving mechanism that drives the main plate; and a control unit that, on the basis of the drive state of one of the slope driving mechanism and the electric winch, controls the drive state of the other.

The invention claimed is: 
     
       1. A mounting device for an object to be mounted, comprising:
 a slope including a main plate body onto which an object to be mounted is mounted, a vehicle-body-side plate body formed by at least one plate body and arranged between one end of the main plate body and a vehicle body, and a ground-contact-side plate body formed by at least one plate body and arranged between the other end of the main plate body and a contact-ground surface, wherein the main plate body is movable up and down between a low position and a high position in a state that the ground-contact-side plate body is in contact with ground; 
 a winch capable of towing the object to be mounted along the slope; 
 a slope driving unit for driving the main plate body; and 
 a control unit that, based on driving state of either one of the slope driving unit and the winch, controls driving state of the other one of the slope driving unit and the winch. 
 
     
     
       2. The mounting device for an object to be mounted according to  claim 1 ,
 wherein, when either one of the slope driving unit and the winch is driving, the control unit prohibits driving of the other one of the slope driving unit and the winch. 
 
     
     
       3. The mounting device for an object to be mounted according to  claim 1 , comprising:
 a slope height detecting unit for detecting height of the main plate body, 
 wherein the control unit switches permission and prohibition of driving of the winch, based on the height of the main plate body. 
 
     
     
       4. The mounting device for an object to be mounted according to  claim 3 ,
 wherein, when the main plate body moves up, if the main plate body is at a position higher than or equal to a first predetermined height, the control unit permits driving of the winch toward a boarding direction. 
 
     
     
       5. The mounting device for an object to be mounted according to  claim 3 ,
 wherein, when the main plate body moves down, if the main plate body is at a position lower than or equal to a second predetermined height, the control unit permits driving of the winch toward an alighting direction. 
 
     
     
       6. The mounting device for an object to be mounted according to  claim 1 ,
 wherein the slope includes plural rotation shafts provided between the vehicle body and the vehicle-body-side plate body and between the respective plate bodies, 
 wherein the mounting device comprises a slope angle detecting unit for detecting rotation angle of the rotation shaft, 
 and wherein the control unit switches permission and prohibition of driving of the winch by the winch driving unit, based on the rotation angle. 
 
     
     
       7. The mounting device for an object to be mounted according to  claim 1 ,
 wherein the winch includes a towing member connected to the object to be mounted and a drum capable of winding back and drawing out the towing member, 
 wherein the mounting device comprises a rotation amount detecting unit for detecting a rotation amount of the drum, 
 and wherein the control unit switches permission and prohibition of driving of the slope driving unit, based on the rotation amount. 
 
     
     
       8. The mounting device for an object to be mounted according to  claim 7 ,
 wherein the control unit computes a draw-out length of the towing member from the drum, based on the rotation amount and thickness of the towing member, and switches permission and prohibition of driving of driving of the slope driving unit, based on the draw-out length. 
 
     
     
       9. The mounting device for an object to be mounted according to  claim 7 ,
 wherein the mounting device comprises a storage detecting unit for detecting a fact that the towing member has been stored in the storing section, 
 and wherein, when the towing member has been stored into the storing section, the control unit resets a detection result obtained from the rotation amount detecting unit. 
 
     
     
       10. The mounting device for an object to be mounted according to  claim 4 ,
 wherein, when the main plate body moves down, if the main plate body is at a position lower than or equal to a second predetermined height, the control unit permits driving of the winch toward an alighting direction. 
 
     
     
       11. The mounting device for an object to be mounted according to  claim 8 ,
 wherein the mounting device comprises a storage detecting unit for detecting a fact that the towing member has been stored in the storing section, 
 and wherein, when the towing member has been stored into the storing section, the control unit resets a detection result obtained from the rotation amount detecting unit.
